Yes, email support and ask for the unlock code, they will make you agree that you know that 3rd party optics may explode the switch and it's not their fault. The command they give you will have a key/hash built into it (but will work on any switch) that ties the "unlock" to your org. Ours looks like this: service unsupported-transceiver DescriptionOfKeyFromAristaGoesHere 0000000000 (hex key) Spencer Ryan | Senior Systems Administrator | sryan@arbor.net<mailto:sryan@arbor.net> Arbor Networks +1.734.794.5033 (d) | +1.734.846.2053 (m) www.arbornetworks.com<http://www.arbornetworks.com/> ________________________________ From: NANOG <nanog-bounces@nanog.org> on behalf of Stanislaw <me@nek0.net> Sent: Wednesday, August 17, 2016 3:50:12 PM To: nanog@nanog.org Subject: Arista unqualified SFP Hi all, Is there a way for unlocking off-brand transceivers usage on Arista switches? I've got an Arista 7050QX switch with 4.14 EOS version. Then it has been found out that Arista switches seem to not have possibility to unlock off-brand xcievers usage (by some service command or so). I've patched /usr/lib/python2.7/site-packages/XcvrAgent.py, made the checking function bypass the actual check and it helped: ports are not in errdisable state anymore. But despite of xceivers are detected correctly, links aren't coming up (they are in notconnect state). If anyone possibly have does have a sacred knowledge of bringing off-branded transceivers to life on Arista switches, your help'd be very appreciated. Thanks.
